Diamond is Unbreakable - Chapter 81 
Heavily wounded by Killer Queen's ability, Shigechi finds himself hunted down by Kira as he frantically tries to find Okuyasu and Josuke. Eventually, Shigechi seemingly escapes the killer and finds the room his friends are in. Just as he grabs the doorknob, however, Kira reveals that he has already turned the knob into a bomb. The bomb immediately explodes, instantly disintegrating Shigechi before his friends can notice. However, the last of Shigechi's Harvest reaches Josuke with one of Kira's suit buttons, having discreetly stolen the button earlier. As Harvest disappears, Josuke and Okuyasu realize that their friend has met a cruel end. Meanwhile, Kira picks up his bag and leaves.
